Lithium-sulfur batteries are of great interest for electromobility applications, among others, due to their high specific energy and relatively low cost, but are challenged by significant capacity decay over cycling. In the lithium-sulfur model, the cathode is composed of elemental sulfur. Earlier post.)

Researchers at Oak Ridge National Laboratory (ORNL) have designed and tested an all-solid lithium-sulfur battery with approximately four times the energy density of conventional lithium-ion technologies. By comparison, a conventional lithium-ion battery cathode has an average capacity between 140-170 mAh/g.

The “simplicity” of EVs in comparison to ICE vehicles allows these disruptors to compete from virtually scratch with legacy automakers, not only in the car market itself, but for the material and labor inputs as well. Tesla is moving towards the use of lithium-iron phosphate batteries, as is Ford for some of its vehicles.
